ATTORNEY pairs sans DEWIS LANDAU, OF SAN STOPPER FOR BOTTLES CO Application filed November 28, 1908.

To all whom it may concern:

Be it known that 1, Dn\ 1s LANDAU, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Stoppers for Bottles Containing Aerated Liquids, of which the following is a specification.

The object of the present invention is to provide a stopper for bottles containing aerated liquids, by tles may be charged with gas more conveniently and at lessexpense than'heretofore.

In the accompanying drawing, Figure 1 is a front view of the stopper, a portion only of the bottle being shown; Fig. 2 is a vertical section of the same; Fig. 3 is a view, similar to Fig. 2, of a modified form of stopper.

Referring to the drawing, 1 indicates the neck of a bottle, upon which is secured a wire band 2, formed with loops 3, which serve as pivotal bearings for the ends 41 of a wire finger piece 5, the latter being formed with loops 6 serving as bearings for the ends of a yoke 7. Said yoke 7 passes through a transverse aperture 8 formed in a metallic stopper 9, in precisely the same way as with porcelain stoppers used with such yokes. he lower end of the stopper 9 is provided with a rubber washer 10, which fits upon the top of the neck of the bottle and makes a tight when the yoke 1S moved to joint therewith, its position closing the bottle. Said stopper is formed at the top with. a cavity or socket 11., from which a conduit 12 leads downward through the stopper to the lower end thereof in order to supply the bottle with compressed gar. The wall of the socket 1 1 is externally threaded, as shown at 13, and upon the same is screwed a cap 14, having at the top a chargin nozzle 15. Within the central aperture of said nozzle can slide a square upper stem disk 18 of rubher being supported upon said valve 17 and adapted to rest against a seat 19 formed by the lower end of the nozzle 15. A spring 20 surrounds the lower valve stem 21 and is contained. within the socket 11 of the stopper. 1

In the modification shown in Fig. 3, instead of the valve 17, a ball valve 22 is used, supported by a light spring 23. However, in certain cases this spring may be dispensed with, and the pressure'of the "fluid contained in the bottle can be depended upon to hold Specification of Letters Patent.

the ball valve 22 to its concave seat 24.

The square upper stem of the valve is formed with a slit 25 to permit the com- 1 pressed fluid to pass to the side of the upper I stem 16. lhe parts of the stopper which i come in contact with the liquid are made of block tin or any other suitable material l which cannot affect the liquidin the bottle. i The particular form of charging nozzle 1 here shown is old, and 1 herein lay no claim l to the same, and it is to be understood that any form of charging nozzle may be used with my present invention.

To fill the bottle, the stopper is opened, the bottle is nearly filled with seltzer water and syrup, or with beer, or with any liquid that it may be desired to aerate. The stopper is then closed by means of the yoke '7 and the charging nozzle 15 is then ap- 1 plied to a charging outlet connected with a suitable source of supply of compressed gas,

and the bottle is held until a sufficient p amount of has entered. JV hen the bottle is removed, the valve 17 or 22 immediately closes and prevents the further escape of fluid. A I In use, the stopper is opened in the ordinary manner, and the contents poured out of the bottle. r By means of this contrivance the bottles l do not have to be sent back to the factory to be filled or charged, but can be readily charged by the retailer with a small ext penditure of time and labor, and at a mini 1 mum of expense. lonsequ ently the cost to l the retaller of these bottles 1s reduced to less than one-half of its former cost. Moreover no skilled labor is now required in operating the charging apparatus, as the bottles are readily charged by any person, however unskilled in the art.

ihe following are present construction. through the stopper 9 at a height slightly l the advantages of the l, above the washer 10, causes the stopper to The yoke 7, passing fit tightly upon the neck of the bottle, so that there is no chance of leakage, and this will be the case notwithstanding considerable variation in the size of the opening of the bottle neck. Since the cap 14 can be readily removed from the stopper, the valve can be at all times kept perfectly clean, so that no leakage can take place.

I claim:

The combination of a bottle, a finger piece, means for pivotally supporting said finger yoke passing through said stopper below said cavlty, said stopper being also formed with a conduit leading from said cavity to the lower end 01 the stopper, a valve in said cavand a cap ity, a springfor raising said valve,

h avlng a screwed upon said stopper, and seat for said valve.

In testimony whereof I have hereunto set 1 my hand in the presence of two subscribing Witnesses.
